What does conformation mean?
Conformation is a noun referring to the structure, shape, or arrangement of the parts of something — most often an animal's body. In equestrian sport, dog breeding, and veterinary medicine, it is a term of art: judges and practitioners evaluate whether an animal's skeletal and muscular build conforms to breed ideals, speaking of good or faulty conformation when assessing soundness, gait, and long-term health. The word also carries an older, more formal sense describing the act of conforming to a standard or model, though this usage has largely given way to words like 'conformity' and 'compliance'. Derived from Latin roots meaning 'to form together', conformation shares ancestry with 'confirm' and 'conform' despite their very different modern meanings. It remains an indispensable technical term wherever precise physical structure matters.
The structure, shape, or arrangement of the parts of something, especially the body of an animal.
"Breeders select stallions for correct limb conformation to reduce the risk of lameness."
Especially common in equestrian, canine, and livestock contexts, where it is judged against breed standards.
The act or state of conforming; agreement with a model, rule, or standard.
"The audit verified the conformation of all components to the required specifications."
Now formal and somewhat dated; 'conformity' is usually preferred in contemporary writing.
Regular plural, used when referring to multiple distinct structures or shapes, such as different molecular conformations in chemistry.
"Chemists study the various conformations a protein can adopt."
In dog shows and horse rings, judges don't assess beauty — they assess 'conformation', literally how well an animal is 'formed together'.

Etymology of conformation
Conformation entered English in the early 17th century, borrowed via French from the Latin verb conformare, meaning 'to shape' or 'to fashion after a pattern', formed from com- ('together') plus formare ('to form'). Its earliest senses covered both physical shaping and correspondence to a model, and both survive today, though the structural sense now prevails. The same Latin root produced English 'conform', 'conformity', and 'confirm' — the latter having shifted semantically from 'strengthen together' to 'verify' — as well as cognates like French 'conformation'.

How conformation is actually used
The structural sense dominates modern usage, particularly in equestrian, canine, and agricultural contexts, where it carries no positive or negative connotation on its own — animals are said to have good or poor conformation. The sense meaning conformity to a standard is now largely confined to formal or technical writing and sounds slightly old-fashioned; writers usually prefer 'conformity' or 'compliance' there.
